Abstract: PURPOSE: To prevent clogging of fine pores in a filter in a process of solid removal to be treated using a porous tube filter by maintaining the ratio of the linear flow  rates of liquid to the filtrate at a value higher than a specified rate.  
     CONSTITUTION: In a process of removing solid material contained in liquid such as clad, etc. generated in liquid transfer pipe line of nuclear power plants, a porous  tube filter is used which is formed of sintered powder metal having a plurality of  fine pores on the wall surface. In this process, under the assumption that the ratio  of the linear flow rate F of solid-containing liquid to be treated and supplied into  the tube filter f to the linear flow rate f of a filtrate passing through the wall of the tube filter, is maintained at higher than 5×10 3 . Said constitution reduces the possiblity of the penetration of the clad into the filter element, and thus prevents the fine  filter pores from clogging.

Title: Device for preventing oil from leaking from bearing of rotary electric machine
Inventor: MINAMI KIYOSHI
IPC: H02K5/16
Filed: 1978-08-21
Abstract: PURPOSE: To effectively prevent lubricating oil from flowing out from the bearing of a rotary electric machine along its shaft by mounting an axial flow preventive insulating ring via slight gap on the shaft.  
     CONSTITUTION: Oil sealing rings 6 are mounted via bolts 15 at a bracket filled with lubricating oil, and an insulating ring 14 is provided integrally formed by welding to the inner periphery of the ring 6. The ring 14 is formed in gap a with the shaft 1. Thus, the oil surrounded by the bracket 3 may not be externally leaked via the gap a between the ring 14 and the shaft 1.

Abstract: PURPOSE:To execute autozooming and autotrimming with which the proper composition of an object is obtained by providing a camera direction control means, a range-finding position control means and an object range decision means. CONSTITUTION:A sequence control circuit 8 transmits a signal to a camera photographing direction alteration means 9 on the basis of the signal of deviation from the center of the position of a remote control transmitter 11 to alter the direction of a camera main body 1 so that a signal from a remote control position detection device 3 may be a central position signal.

Title: Shaft joint
Inventor: SAKAI YOSHITAKA
IPC: F16D3/48
Filed: 1985-05-14
Abstract: PURPOSE:To enable improvement of power transmission performance and durability through absorption of axial vibration and friction, according to the method wherein a coupling is coupled through the one end of a pin, and the other end is rotatably connected to the coupling. CONSTITUTION:Since a pin 5, inserted in couplings 3 and 4 secured to shafts 1 and 2, is freely rotated and slid, a change in an angle due to axial vibration of shafts 1 and 2 and displacement of an axis is absorbed. Further, since the one end of the pin 5 and the one coupling 3 are interconnected in a way to be capable of rolling in a state to axially nip a groove 8 therebetween, a change in angle extended at right angles with and in the direction of the axes of the shafts 1 and 2 is absorbed. Thus, a shaft joint is excellent in resistance to friction and vibration, and performs efficient absorption motion.
